Use with Micro Focus Products

  • If a region is hosted within a container which does not or cannot expose its internal network addresses, the Micro Focus Enterprise Server Common Web Administration interface will be unable to connect to the started region's ESMAC/monitor configuration unless the MFDS_EXTERNAL_ADDR environment variable is set within the container to an externally contactable address.
